Subject: [PATCH v22 08/18] dt-binding: memory: pl353-smc: Enhance the description of the reg property

The SMC bus controller features several register sets. The one pointed
by the reg property is for the SMC configuration (impacts the
sub-controllers configuration), while the others are meant to be used to
send regular cycles on the memory bus (eg. CMD, ADDR, DATA for a NAND
device). Detail this a little bit for the sake of clarity.
